Answer:
5n^2+(4n)-1
Step-by-step explanation:
(5n-1)(n+1)=0
Lets find <em>n.</em>
(5n-1)(n+1)=0
FOIL it.
5n^2+5n-1n-1
Add/Substract similar factors
5n^2+(5n-1n)-1
5n^2+(4n)-1
Thats your answer.

Step-by-step explanation:
Given:
Rosa has to skate around a face off circle five times.
Diameter of a circle = 9.0 m
Radius of a circle = 
Solution:
We know that the circumference of a circle.
Where;
r = Radius of a circle
Substitute 
in above equation.
So, the circumference of the circle is 28.26 m.
Rosa has to skate around a face off circle five times, so Rosa cover 28.26 m 5 times.
Therefore, the distance cover by Rosa to skate 141.3 m.
A) Tonya bought 3 games at X price, so 3X would be total amount.
B) Tony's cost was 0.50 less than X, so x-0.50, he bought 4 games, so he spent 4(x-0.50).
C) Set those to equal to solve for x:
3x = 4(x-0.50)
D) Solve:
3x = 4(x-0.50)
Distribute:
3x = 4x - 2
Subtract 4x from both sides:
-X = -2
Multiply both sides by -1:
X = 2
E) Since X is the amount Tonya paid per game, Tony paid X - 0.50, so Tony paid 2 - 0.50 = $1.50 per game.
Check:
Tonya: 3x = 3(2) = $6 total
Tony: 4(x-0.50) = 4(2.00 - 0.50) = 4(1.50) = $6 total
